POWDER-GAS BOILER FOR ENGINES.

SPECIFICATION forming part of Letters Patent N 0. 405,229, dated June11, 1889.

Application filed September '7, 1888. Serial No. 284,838. (No model.)

To all whom it may concern.-

Be it known that we, OTTO SCHNEIDER, a citizen of the United States,residing at Louisville, Jefferson county, Kentucky, and HEIN- RICHSCHNEIDER, a subject of the Emperor of Germany, residing atOberstein-on-the-Nahe, Rhine Province, Germany, have invented certainnew and useful Improvements in Powder- Gas Boilers for Engines; and wedo hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

Our invention relates to a powder-gas boiler.

By filling a strong boiler with the gases produced by an explosion ofpowder a much greater pressure can be obtained than by using steamproduced from water. This pressure can be used advantageously tofurnish.

power for engines of vessels, as it will permit the economizing of thelarge space now used ,the explosion of powder as a motive power formachinery.

Our invention consists of an apparatus adapted to utilize as motiy epower the explosive force of gunpowder, having, in combination, a boileror gas-holder, a feeder or generator connected with the boiler by avalved passage-way, and an electric battery for explodin g the powder.

In the accompanying drawings, Figure l is a front elevation of ourapparatus in connection with an ordinary engine. Fig. 2 is a verticalsectional view of the boiler and feeder with elevation of engine.

Similarletters refer to si milar parts thro ughout the drawings.

A is a strong boiler or gas-holder provided with pressure-gage a,safety-Valve a, and gas to the engine to be actuated.

B isa feeder, and it consists of a strong metal casting, solid in itsupper part and hollow in its lower part, on top of which is placed afunnel-shaped hopper F. From front to rear,

A circular hole or shaft f through the casting connects the cell inwhich 0 revolves with the lower aperture of the funnel, and a similarshaft f connects the cell with the explosion-chamber b, occupying thelower portion of B. I

D D D D are cells of a battery, placed as convenient, with the wires dand cl forming the circuit, and held in such a position by the standardK that the circuit can be closedat the point H by the thumb g on thewheel G.

The wire cl, properly insulated, carries the circuit through the wallsof B and through the explosion-chamber, having in the circuit, withinthe explosion-chamber b and under the opening of the shaft or hole aiece of platinum wire p. i

G is a spur-wheel, the axle of which is also the axle of cylinder 0,which revolves with it, and g is a thumb or comb projecting from oneside of its circumference. be provided with a crank and handle, so as tobe turned by hand, or may be geared with a wheel 6, so as to be turnedby a belt 6 from an engine E.

O is a valve-chamber connected by pipes c 85 c with the explosionchamber1), and the receiver A, and having in it a reactive valve 0.

The working of my invention may be described as follows: The powder isplaced in the funnel-shaped hopper F. Power is ap- 9o plied to the wheelG, which revolves, carrying the cylinder 0 with it. When the recess 0 isbrought under the aperture of the funnel,

powder is passed into it through the shaft f, and when it is carried itis emptiedand the powder falls into the chamber 12 and onto the platinumwire 19, heated by the closing of the circuit at H by the thumb g, andis exploded; The gases generated by the explosion force their way 10othrough the valve 0, which is reactive, and closes again after they havepassed into the The wheel G may round to the shaft f 9 boiler A, fromwhich they can pass as required through the pipe at to the engine to beactuated.

Having thus explained my invention, what 5 I claim as new, and desire tosecure by Letters Patent, is-

A powdergas boiler for engines, consisting of a strong boiler providedwith pressuregage, safetywalve, and exit-pipe, in combina- IO tion witha feeder or generator consisting of a strong casting with a circularcell through it, a cylinder with a recess in it fitting closely in thecell, an explosion-chan1ber in the casting below the cell, a valvedpassage-way con- I 5 necting' the explosion chamber with the boiler, afunnel on the casting, ashatt or hole through the casting from the pipeof the funnel to the cell, a shaft or opening; from the cell to theexplosion-chamber, a wheel turning 011 the same axle as the cylinder andfur- 2o nished with a proj ecting thumb to close the electric circuit,and an electric battery to we plode the powder, substantially asdescribed, and for the purpose specified.

In testimony whereof We aflix our signatures 2 5 in presence of twowitnesses.
